ls1043 with lan8814 qsgmii

Hello NXP Team,

I use eval board ls1043 ardb CPU with LAN8814 chip.

but qsgmii netwok Interfaces still working.

I use also other board with ls1043 CPU but with LAN8814 Chip.

Its possible also to use LAN8814 inside SDK_DPAA?

For debugging you can use CodeWarrior, on the other hand if you want to check the sent/received frames you can use the WireShark app.

the first thing is to have the driver added as a module in the Kernel, then you need to select it by make menuconfig

FYI, the LS1043ARDB use the F104S8A PHY for the QSGMII.

It is not possible

ls1043ardb board use VSC8514 QPHY with DPAA Ethernet:

Using SERDES1 Protocol: 5205 (0x1455)

My board use LAN8814 QPHY:

Using SERDES1 Protocol: 13397 (0x3455)

linux driver micrel.c -Phy Address 4 - 7 is added in device tree

I use this Linux https://github.com/nxp-qoriq/linux.git with branch lf-6.6.y and commit id is

d23d64eea5111e1607efcce1d601834fceec92cb.

I think this is the newest NXP Linux kernel and the micrel.c driver is also new.

Why you think is not possible to use ls1043 with LAN8814 QPHY?

You mean hardware combination ls1043 and LAN8814?

or

You mean software also u-boot, rcw, linux etc.?

or

you team don't have time to check this?

dear radebozic,
it isn't posible to add the driver to the DPAA firmware, on the other hand, regarding your general schematics, I have to say that configuration is posible adding the respective driver to the kernel. Keep in mind if you want to get a better performance you will need to get access to the DPAA hardware trough your own driver.

Many thanks Luis Fernando and I understood your description. Of course I have to adapt the linux (device tree and the driver) to my hardware design and hardware settings.

Nevertheless, I would like to know how do I have to adapt/config the latest kernel (https://github.com/nxp-qoriq) to use the hardware LAN8814. We have 2 dpaa drivers, one with Bman and Fman (sdk_dpaa) in staging (drivers/staging) mode and other one fman driver in driver/net/ethernet/freescale without staging.

Maybe you can give me i hint how i can check and debug the dpaa?

Or, what exactly do I have to pay attention to when sending and receiving via DPAA?

FYI: I really expected it to work with the latest Linux kernel without staging driver.
